alright i got a 1990 240sx fastback, the owner told me that the headgasket was cracked so he replaced it very quickly he said and also that it problay didn't seal good. so i bought the car for $140 dollars and it came w/new fender, le bra, and a new hub cap, i mean the car looks good cept some dents but nuthin major and we drove it like 10 miles but it was smokin like a mug and then it finally wouldn't start and he also told me that colant was mixing with the oil. all i need to kno is an opinion on how to fix this and how much if i do it myself btw the head is probaly warped and the motor is the ka24e thanks for all your help

 

Sounds to me like you got quite the junker. I would save the troubles and just get another ka or whichever motor you want.

yeah, the HG is blown,thats for damn sure. If he's already fixed it once, i'd say upgrade to the DE, or you could try replacing the gasket and machining it, but for that price you could probably find a good working DE for cheap and drop that in, although there's a few more things you gotta do to make a DE work in a 89-90. Maybe you could find another E?

alright i will try to fix it

 

dont be foolish.
coolant mixing with oil is torn water jacket in the timing cover.
you need a timing kit and cover
the chain gets lose and eats up right nest to the water pump,
in front of the thermostat housing.
the headgasket will need to be changed agin if you dont stop driving it.
my 90 240 did the same thing lst year. and the timing was so off that it wouldnt start.
i would check this out before you give up like a little ***** and sell the car. once you make the decision to become a 240 owner you will have to deal with stuff like this.
240's turn boys to men
and some men to ricers

what one are you gona be?

 

...............Need I say more?

Also what color is the smoke? White, blue, gray?

Robbie

 

Ouch, poor guy is gonna cry now, lol.

Dr.

 

alright i wasn't gonan give up i was gon na just buy the DOHC motor and btw the smoke was white didn't see any blue or other colors

 

Well 9 out of 10 times when you have a blown head gasket itll puff out a blueish smoke. For example, if you see people who own chrysler mini vans, the older ones..... they are PRONE to blow head gaskets and thats why you see em puffin out blue smoke. Just an example. So most likely the gasket is fine.
Rudeboy sounds rite about the water jacket. So check it out.

2 words
compression
test

 

yeah, 2 very well chosen words rudeboy!
search for the how to and results, bascially if they are more than 10 apart from each other then it's bad, you'll have like 168, 160 145, 171, like that.
